PRODUCTION DATA
The McBSP module has the following features:

where CLKSRG source could be LSPCLK, CLKX, or CLKR. Serial port performance is limited by I/O buffer switching speed. Internal prescalers must be adjusted such that the peripheral speed is less than the I/O buffer speed limit.
See Section 8.9 for maximum I/O pin toggling speed.
On the 80-pin package, only the clock-stop mode (SPI) of the McBSP is supported.
Figure 8-38 shows the block diagram of the McBSP module.
Figure 8-38 McBSP ModuleTable 8-29 provides a summary of the McBSP registers.
